棉花采用助壮素(DPC)系统化学调控是促使棉花增产的一项重要技术。运用该项技术,可克服南方棉区在生育前期棉株徒长、落蕾落铃和中倒伏、烂铃、“秋发”返青等问题,能形成棉株高95厘米左右、果枝长33厘米左右、单株体积缩小15～25%的高产理想株型。余姚市农技推广总站1990年以来,在本市棉区进行的多项多点助壮素调控试验示范,显示出有
Cotton using mepiquat chloride (DPC) system chemical regulation is to promote cotton yield an important technology. The use of this technology can be to overcome the southern cotton area in the premature growth of cotton plant leggy, fall and fall bell and lodging, bad bell, “autumn hair” back to green and other issues, to form a cotton plant height of about 95 cm, fruit branch length of about 33 cm , The plant volume reduced by 15 ~ 25% of ideal plant type. Since 1990, Yuyao Agricultural Technology Extension Station has carried out a number of pilot experiments on the regulation and control of meiotropin in the cotton area of this Municipality, showing that there are
